Since creating an EmuNAND partition through SX OS when booting now it can't find my boot.dat file despite it being on the SD card. testing a non emunand SD card works fine

This is going to sound stupid, but on your emunand SD card, is the boot.dat file still on the root of the card?

Yes it is. SD card contains a boot.dat license.dat and an sxos folder with xci's in

Are both SD cards formatted fat32 or exfat?

card that works is exfat. card that doesn't is fat32 (although does SX OS reformat it on creating the emunand partition?)

Hmm. Was thinking maybe exfat driver, but if the one that works is exfat that isnt the issue. It should not from what I have read, but I have not tried myself. I would try re-downloading the boot.dat file from the website and see if that fixes it. You can also try reformatting just the data partition on your SD card. Maybe something happened when SX repartitioned the SD card. That should not effect the hidden emunand partition.

What I might do is reset the SD card and try it without emunand to rule out a broken card. will report back if it works/doesn't work

Ok I tried the fat32 SDCard with no EmuNAND and it worked fine so the emunand is definitely the problem. Just to check, once emunand partition is created you put content on the TXNAND partition right? (the other partition doesn't show up)

After creating another emunand I can reproduce this bug. SD card works fine without emunand. Apply emunand and on reboot it can't find boot.dat (even though it's there). This time I didn't even touch the files on the SD card, just rebooted after emunand was created

EDIT: worth noting this is a 64GB toshiba exceria micro SD card, in case that's important

Yes. I just did this last night on my 128gb card and the only partition you will see is TXNAND. That's where the files should go.

After creating another emunand I can reproduce this bug. SD card works fine without emunand. Apply emunand and on reboot it can't find boot.dat (even though it's there). This time I didn't even touch the files on the SD card, just rebooted after emunand was created

I am using a 128gb sandisk. I am not sure that it matters the brand as long as it not one of those no name brands. Do you have a bigger card to try? I have a 64gb that i will try today to see if I can reproduce your issue.

Have you found a solution for this? I have the same problem :(
I tried several options but neither of them can make detect the "boot.dat" apparently.
If I use the "Files on MicroSD Emunand" it works fine.

I wish I could give more options, but I setup emunand with the partition on a 128gb SD and it works fine. No issues reading the boot file or anything. It surely sounds like something with the SD cards or the size.

Is there any news on this? Im trying this right now with a 32 GB Samsung EVO Plus. The moment i created the emunand hidden partition, sx os cant find boot.dat anymore. SX OS 2.5.2

Do you have a larger SD to try? Emunand is basically a copy of the internal nand which is 32gb. So I am not sure a 32gb SD will work since it would then make the whole card the emunand.
